Question Problems with IBM Portable Drive Bay and CD-ROM 

Forum: PCMCIA ATA/IDE Device Issues
Date: 2000, Mar 18
From: Sten Drescher StenD

I'm attempting to use a CD-ROM drive in an IBM Portable Drive Bay with my ThinkPad 600. SUPPORTED.CARDS indicates that this has been tested, but I'm having problems with it. The HOWTO indicates that there may be problems configuring the drive if there is no media present at insertion time, but I'm still having problems despite having a CD in the drive. I typically have to issue `cardctl eject 0; cardctl insert 0` to get the ide channel recognized:

Things seem to work fine after this, but I have trouble later unmounting the CD. I see the following messages in /var/log/messages at that point:

As I said, this is an IBM ThinkPad 600, type 2645-85U. I'm using the IBM Portable Drive Bay (FRU 37L1513) with the IBM IDE PC Card (33L5033) and an UltraslimBay CD-ROM (05K9267). Any assistance anyone can provide would be welcomed.
